Ignore line length in test descriptions

[vuki656]

Currently, eslint reports an error if it('should bla bla line in tests exceeds the max-len of 120 characters. As there is no way to go around this in a clean way, max-len rule should skip checking the it('should bla bla lines.

If there is a it('should bla bla line in tests that exceeds the max-len of 120 chars, it should not be reported by eslint.
